BOSCH 50011479 QuietCast Premium Disc Brake Rotor - Front, 328mm (Single)

I installed this Bosch QuietCast rotor on my Toyota, and I’m very impressed with the quality. The rotor fit perfectly, installation was straightforward, and braking performance improved immediately. It runs smooth and quiet with no vibration or pulsation, even during hard braking. The protective coating is a nice feature and should help prevent rust over time. Bosch continues to deliver reliable, high-quality products. I would definitely recommend this rotor to anyone looking for an OEM-quality replacement.

These rotors were a perfect fit for my 2012 Toyota Sienna. No issues during installation and performance has been great so far. Highly recommend.

I’ve put 2000 miles on the rotors already doing Rideshare in Las Vegas and they are great lots of quick stops I’ve done some spirited stops off freeway ramps to test fade and paired with good pads they have been great. Very quiet, very smooth. I love the cooling holes in the rotor hat. Still no rust and they have been through two rain storms and about 10 car washes. When I get to 10k miles I will see if it’s still as good as now. Pairing these with OEM or higher quality pads will make all the difference. I’m very pleased and would buy these again.

I installed Bosch disc rotors in 2020, after 40 K miles in 2025, I purchased those again as part of front brake repair, I found out the 2020 installation is still in good condition. So I do not have to replace them. But I missed the chance to return them, maybe a good thing just look at the inflations. Bosch rotors and the brake pads are good combo. They provide confident stop power on my Sienna. Highly recommended.

Fit was Perfect. No Vibration or squeaking. Easy to install. However, these rotors overheat all the time in mountain driving. Steep hills but limited extra weight….and we drive well below the allowable speed. Overheating meaning rotors get very hot…. surface color changes… and smell is pungent. I previously used Bembro and Toyota rotors and pads with much better results. I bought Bosch as I did not want to wait for the lead time of other brands. That was a mistake. Two stars are solely based in fit and finish. I assume the metal is a sub-grade composition.

Perfect

Just what my Toyota needed

I have been buying these rotors for my 2010 Lexus RX 350 for a couple rotations now and I feel these are just as good as OEM. I experience smooth braking and no vibration when breaking. I do notice they rust but not sure how that compares to OEM as I’ve seen rust on those too. I sometimes have noticed my brakes squealing a little bit but that goes away after they warm up. Other than that I have no complaints and they are cheaper than OEM. I feel confident with these rotors on my vehicle.

Installed a few weeks ago and very happy so far. Initially the pedal was very soft, but once broken in and the coating was worn a very smooth, solid feel returned. No vibration or noise. Lack of preservation oil makes installation faster and less messy. Rotor fit properly, and includes the same threaded jacking holes as the oem part.

After 6 months of use these rotors have worked as well, if not better than OEM. Added value over OEM is the anti-rust coating that keeps the rotors looking decent. The only beef is that the description was ambiguous on whether item is sold in pairs or singles. Seems to be a common issue with items that are generally purchased in pairs.

Good quality, no rust at all after the first winter!

Fit well, stops the vehicle. All in all great purchase.

not good, Create a Squeaky noise, in the very first week
